Okay, putting on my sea-lawyer hat here, bear with me:
Would a lawyer defending a veteran, especially one who was enlisted, be able to put the Federal prosecutors in a catch-22 by claiming they were following what they believed to be a lawful order from a sitting President in defense of the constitution?
Would that put a judge, especially one who was a Clinton/Obama appointee, in the position of acknowledging personal liability for the actions of the rioters on the 6th, if they disagree with that argument? If you find the rioter was acting under their own volition, and not under the orders of a sitting President, does that not then absolve said President of culpability and set a precedent for any future liability defense for said president?
Woukd be an interesting argument to see from a creative lawyer...most of the people who did nothing more than illegally enter would be risking, at worst, a wrist slap either way...
